Tech
The following is cited from snapshot64.c found at the VICE project page:
Snapshot 64 (LMS Technologies)
FIXME: this implementation is purely based on guesswork
- 4K ROM (2732)
- mapped to 8000 and e000 (ultimax mode) ?
- NE555, 7406, 7474
- one button (freeze)
io2 - df00 (r/w)
0 - cart off
1 - cart enabled
after reset NO menu is shown. when pressing freeze the screen goes blank, then
return - starts the "code inspector"
l - load and execute ml program
j - jump to address
d - dump memory (hex)
e - return to basic
f1 - analyze and save backup
f3 - clear memory
f5 - format disk
f7 - restart

io1: (read/write)
cart ram
io2 (read)
df01 - ram config

io1 (write)
df00/df01:
